# Axon Supported Chains List

> Axon Supported Chains List is a paid API for AI agents from aiaxon402.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a mapping of supported blockchain chain IDs to their human-readable names (e.g. Ethereum, Base)

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability axon-supported-chains-list-7dc79006
```

Example prompt: What blockchain networks does the Axon crypto intelligence API support? I need to know the chain IDs and their names before I start querying for token data.

## When to prefer this

Use this endpoint first when you need to discover which blockchain networks the Axon platform supports before making token research, market analysis, or contract auditing calls. It serves as a reference lookup for valid chain IDs to use in other Axon endpoints.

## Known failure modes

- Payment failure: x402 micropayment of $0.01 USDC on Base not completed, returns 402 Payment Required
- Network error: upstream service unavailable, returns 5xx
- Empty or partial chain list if the service is misconfigured

## How this service works

Axon provides AI-powered crypto intelligence endpoints covering token research, market analysis, contract auditing, sentiment tracking, news summarization, portfolio advice, deep research, text translation, language detection, SEO content generation, and contract explanation. All analytical endpoints require x402 micropayment on Base.

## Output

A JSON object with a 'chains' key mapping numeric chain IDs (e.g. 1, 8453) to their human-readable blockchain names (e.g. 'Ethereum', 'Base'). Useful for discovering which networks are available before making subsequent token research or market analysis calls.
